I assume you're using Subtotals to count the number of values in each subsection. You can create a conditional format to check for "Count" in column A like so:
You'll just highlight all the cells in column B that apply, add the conditional formatting rule as shown above and then note the formatting change (bold, red font).

NOTE: if you remove/re-add subtotals, the formatting will likely not appear. You'll have to edit the conditional formatting rule again to ensure that it has the formula =RIGHT($A2,5)="Count"
